When someone believes that a fetus constitutes a human life there is nothing you can do to change their mind about it. They feel very strongly about as they believe that it is government sanctioned murder of an innocent. Abortion will always be a divisive issue and will maintain the GOP's power on its own.The usual then, I'm glad to hear your mom voted her conscience - hope it's not causing too much friction :/
My parents are conservative as well (and have some shitty ideas) so I know how you feel. I'm trying to slowly get through to them, though, which I guess is a little easier in Europe since we don't have Breitbart and Fox.
Abortion being such a wedge issue is such crap though, in general.
